Default Cutting irregular hole in panel

Mods, please move if this is not in the right place.

I've finally found a steel box to put an isolation transformer in, the front panel is what appears to be 1mm steel. I want to put a standard MK mains single socket on the panel, which entails cutting an irregular hole - almost square, but not quite.

What is the best way to cut such a hole (there's also a rectangular one needed for the on/off rocker switch)? I've got no fancy metalworking tools, just a power drill, vice, hacksaw and files.
